Claims.

This invention relatesto line indicators when copying a, manuscript or other material, or whenwerking on an accountants sheetv or book or the like, and it also: aims to combine such a device with a. holder for the copy or sheet on which the lines are; to be; indicated by the device.

As it is well. known, when a manuscript or other original to. be copied, like by a typist, and also: when accountants work on sheets or books of aceounts, a ruler or the. like is. placed at. the line to which the work. progressed, as otherwise, repetitions, omissions, or other mistakes may occur; At present, simply a ruler, an eraser, or. any other object is. placed. at. the line tov which. the work progressed, to know where to take it. up, again, and it is obvious that such a flimsy, make-shift indicator: or marker is adapted to. change its position, and to slip, whereby it will defeat its. own purpose. Such indicators, for thepurpose mentioned, are also objectionable, as they do not indicate the line or the place with the clearness and exactness required in some work, and the line or item arrived tov as the work progresses, cannot be easily and. clearly observed.

The main object of: my invention is to. provide. a. device. for indicating lines or places arrived to in. copying or in working. on accounts and the like,. which will be. morev efiicient that. those now in use or heretofore proposed.

Another object of my invention is to provide a. device: of the type. described, which will be less. complicated in construction than some of the: devices; proposed for this purpose, and which. simply may be placed on. the sheet or book, a portion of. which is to. be marked, and. still will: remain. in place in a reliable manner, indicat.- ing. that place, and. which also. may be removed. with the same ease and facility.

. Still a; further object of my invention is. to provide a device, as characterized hereinbefore, which will be; adapted to beclamped on a sheet. or several sheets, or a book. and the. like, worked on,,whereby it will. hold such a materialagainst movement.

Still further objects of my invention will be. apparent as. the specification of. the samepro.- ceeds, and, among others, I may mention: to;

provide a: device at the mentioned character:

which will be simple in construction-,finexpensive; vand. adaptedto. massma-nufacturing- With the mentioned and. other objects. in. View,

my invention mainly:- consists in providing an,

elongated weight which is adapted to be placed atone. side of. the sheet or book worked omand on which an indicator arm may slide, Said. weight also may include a telescopical inner weight, whereby the length of the same. may be.

Fig. 4 is afragmentary sectional detail, the sec'-' tion being taken on the line 4-4 of Fig. 2;

Figs. 5 and 6 show details of a modification. Referring now to the drawings more in detail by characters of reference, the numeral I'll ihdicates my device, in general, being placed ona sheet to be copied or to be worked on, indicated by the numeral II, and having lines or otheritems 2.

The main element of my device is abar I3, having considerable weight, and slidable in an inverted U-shaped sleeve or jacket Hi.

It will be seen that the weight has arelatively narrow base 15, and comparatively high side walls I6, while the top ['1' of the same is rounded.

To make the same easily slidable in the shell or sleeve l4, said sleeve is loosely arranged therearound, but the base weight l3 will have a groove or indentation [8,. at each side of the same, and the outer sleeve: 01" shell I4 will have a registering indentation I9, whereby the inner weight l3 may easily slide inwardly or outwardly of" the sleeve M, as indicated bythe double arrow 20, but it still will be guided in its movements and will keep the outer sleeve [4 in the desired fixed sheet II', but in close proximity to the same, so

as to be adapted to mark any item orline: l2, 'as will be understood. Band. 2| may have indentations'23 to better secure its position on the sleeve.

l4 andon thebase weight l3, when it. will be sliding thereonto, as will be explained presently.

Thetop' portion 2 lb of the band 2 i is considerably-spaced apart from the top H of the sleeve;

and, of course, fromthe top |3a of the base" weight I3, and a spring wire 24 is secured thereinto, adapted to press downwardly on said sleeve, or on the base weight I3, thereby assuring the position of the band by frictional action. The band, namely, will have inwardly projecting rounded portions 25, to the rear of said indentations 23, and opposite the groove I8, in the base weight, and I9, in the sleeve I4 respectively, and thereby an upward movement of the band 2I will be prevented. A felt, or rubbensheet 26 also may be secured on the bottom I5 of the weight I3, whereby slipping or sliding on the sheet II will be prevented, in addition to the frictional action of the weight itself.

The use and arrangement of my device for the purpose mentioned will be obvious from the herein description, and from the drawings.

The weight I3, entirely telescoped into the sleeve I4, will be placed on one side of the sheet II, in Fig. 1, the right side being indicated, on a free marginal portion thereof, having no text, figures, or any other material on said margin, As the copying or observing of the items progresses, the band 2| will be moved downwardly along the sheet or page II, as indicated by the arrow 2 and the arm 22 will indicate the place where the work has to be resumed.

The pressure of the spring 24 may be selected in such a manner that the band 2I may comparatively easily slide on the sleeve I I, but said spring will fix it in the position to be moved.

When the sheet II is longer than the sleeve I4, the base weight I3 will be moved out from the same, as indicated by the dot and dash lines in an imaginary manner at I3b in Fig. 1, and when the indicator 22 arrives to the lower end Ma of the sleeve, it then continues its downward movement over the extension weight I3.

A band 2I will have the rounded portion 25, riding in the grooves I8 and I9 respectively and by its rounding in both directions, the band 2I may easily move from the sleeve I4 to the weight I3, or, vice versa, in the other direction, when it is desired to again contract and telescope the device.

When the band 2I rides on the Weight I3, the spring wire 24 will move somewhat downwardly and still retain a pressure on the weight I3. To

allow such a movement for the spring 24, a slot or window 28 will be provided in the band 2|, the outer end 240. of the spring being allowed to move upwardly and downwardly in said window.

My device is adapted to be placed on the left hand side of the sheet I I, when desired, said place for the same being indicated by the numeral 29.

In some cases, the right hand side of the sheet will not have sufiicient free margin to place the indicator weight bar thereon, and the left hand side may allow such a placing of the same without interfering with the material on the sheet. In such cases, band 2| will be entirely pulled of! the sleeve I4, whereupon the weight with the sleeve on it will be placed on the left side margin of the sheet, as indicated by 29, and the band 2 I, pushed thereon in a reversed manner, so that arm 22 will then point to the right of the weight bar, instead of pointing to the left, as now indicated in Fig. l.

The use and operation of the device will be identical as described with reference to said righthand original position of the same.

Finally, I also may provide means whereby my device, in addition to its weight, may also be clamped on the sheet II, or on a book, if such is the object worked on, or, indeed, may clamp the sheet on the book to a supporting element like the top of a desk. For this purpose, the sleeve I 4 may have narrow extensions 30, and a spring clamp 3| may be pushed over them and underneath the sheet, book, or other object 32, and in clamp 3| will be employed in an opposite direction. Indentations 33 may also be provided at the outer end of the weight I3, to facilitate its moving inwardly or outwardly on the shell II.

- While I have shown preferred embodiments of my invention, it is to be understood that changes and variations may be resorted to in the elements, construction and combination of it, and I reserve my rights to such changes and variations as are within the spirit of this specification, and the scope of the claims hereunto appended.

One such change is shown in Figs. 5 and 6, and, as will be seen, a sliding slip 34 may be arranged on the arm 22, in case it is desired to indicate not only the line to which the work progressed, and which is indicated by the arm 22, but also indicate on said line an item to which the slip 34 may be pushed on the arm 22, as will be under stood.

What I claim as new, and want to protect by Letters Patent of the United States, is:

1. A line indicator comprising, in combination, a substantially heavy bar having a plane base,

- being substantially higher than the width of its base and adapted to be placed on a page of a book or a sheet of paper or other material by said base, a resilient loop of a strip of material encircling the top and sides of said bar, the lower ends thereof being slightly above said base, and

said strip being slidable on said bar while pressing on its sides, and a lateral arm bent out to one side from said strip at one of its lower ends whereby said arm is adapted to indicate a line on said page of a book or sheet of material.

2. In a device, as set forth in claim 1, the top of said loop bein spaced apart from the top of' said bar, and a downwardly curved flat spring adapted to slidably press on the top of the barsecured by its ends in the top of said loop, whereby said loop will be removably secured in its various positions when sliding on said bar by the frictional action of said spring on the top of the bar.

3. In a device, as set forth in claim 1, longitudinal grooves in the sides of said bar and corresponding beads in said loop, in complementary sliding engagement with said grooves.

4. In a device, as set forth in claim 1, said loop being entirely removable from said bar by sliding it off the same and being adapted to be similarly replaced in a reversed position, its arm pointing oppositely, whereby said line indicator may be employed on either margin of a sheet or a book and the like.

5. In a device, as set forth in claim 1, means at one end of the device whereby to clamp it on said page of the book or a sheet of material when desired.

6. In a device, as set forth'in claim 1, said barhaving a top and two sides, an outer shell encircling the top and the two sides of said bar, said bar being slidable therein, and said resilient loop being adapted to ride on said outer shell,

or on said bar when pulled out from said shell.

7. In a device, as set forth in claim 6, a longitudinal groove in said bar and a complementary bead in said shell telescopically and slidingly engaging one another, and said spring loop having asimilar bead adapted to slide in the groove of the bar or in the bead of the shell.

8. In a device, as set forth in claim 6, indentations in the sides of said bar in an end portion thereof, usually projecting from said shell, said bar being adapted to be gripped at said end thereof through said indentation for slidably moving the bar inwardly of or outwardly from said shell.

9. In a device, as set forth in claim 6, the top of said resilient loop being spaced apart from the top of said shell and said bar, and a downwardly ous positions when sliding on said shell or on said bar by the frictional action of said spring on the top of the shell or of the bar.

10. In a device, as set forth in claim 5, said means consisting of extensions at the end of the shell adapted to be clamped, as recited.
